[R] Simple table with frequency variable

[casot at libero.it]

I have to compare four different grape varieties proteome in two different years. I don't know what test would be more suitable for my data. I think that an anova two way can be usefull also if someone suggested me to perform a manova. In addiction, I can perform each test on a single protein a time, but I can't loose my whole life carrying out anova (I have more than 1000 protein to analyze)!!! I would like to perform the test on every column of the dataframe in a single run. How can I do that? I attach an example of some protein of my dataset
